FLYBACK REGULATOR CIRCUIT EXAMPLE
The circuit of Figure 44 produces ±15V (at 225 mA each) from a single 5V input. The output regulation of this
circuit is shown in Figure 45 and Figure 47, while the load transient response is shown in Figure 46 and
Figure 48. Switching waveforms seen in this circuit are shown in Figure 49.
